Dear Yutaka, I would like to renew an old request of mine. It essentially boils down to two related enhancements: * Replace the patch of color representing the marker on the marker toolbar with two “buttons”, one above the other, where the upper one shows an UP-ARROW and the the lower one, yes you guessed, a DOWN-ARROW. Clicking the upper one will be linked to the “Find previous” function wearies clicking the lower invokes the “Find next” one. * Whenever one customizes the marker’s color in the “Display” tab of the “properties”, it should also change the background color of the above two buttons, or at least the patch color on the markers toolbar.
